So What?
1) The Organisation for Economic Co-operation and Development (OECD) compiled data for life expectancy at birth and the
number of nurses per 1000 people in the population (physician density) in several countries.
2) No results were collected for Japan, Greece, Switzerland, or the US.
3) Generally, most results group around 77.5 to 80.5 years of age and 5.5 to 15 nurses per thousand population. That's within a
three year window with a nurse density range of nearly three-to-one.
4) Within this grouping, there is a slight positive correlation between life expectancy and nurse density. (Longer life related to
more nurses.)
5) Interestingly, Iceland has the highest life expectancy of approximately 81 years and has both very high nurse density at about
13.7 per thousand population and very high physician density of 3.6 per thousand population (see physician density chart).
6) Notice how Spain maintains nearly the same life expectancy as Sweden and Australia with 29% lower nurse density (7.5 versus
10.5 per thousand population).
7) Surprisingly, Korea maintains a life expectancy the same as Portugal with less than half the nurse density and nearly the same
as Luxembourg with less than one-sixth the nurse density.
